the outside diameter of the sleeve 24 soas to provide an annular passage 32v therebetween. A

' threaded connection 33 between the cap and the sleeve 24 is provided above the port 28 to enable the cap to be threadedly held in place with its l upper end tightly abutting against the lower side of the ange 26. The depth of the interior of the cap is greater than the length of the sleeve 24 below the flange 26 so that the iower inner sur-` face of the cap is spaced from the lower end oi the tube I8 and sleeve 24. This enables communcation between the bore 30 of the smoke tube I8 and the annular passage 32.

By the` construction above described, when suction is exerted on the mouthpiece end of the stem I2, the smoke will be drawn from the in terior of the bowl downwardly through the bore 30 of the smoke tube I8, thence through the space between the lower end of the tube I8 and sleeve 24 and the cap 29 into the annular passage 32 and through the port 28 into the annular smoke chamber 2l', and thence upwardly and into the stem passage 22.

It is thus seen that the smoke rst travels downwardly the entire length of the tube i8, thence laterally to the annular passage 32 and through this passageway to the radial port 28 into the annular chamber 2, and thence upwardly around the smoke tube I8 to the stem passage 22. In this manner the length of the travel of thel smoke is appreciably long so as to permit adequate cooling of the smoke by the exchange oi heat with the metallic surfaces contacted by the smoke in its travel, and, consequently, when' the smoke enters the stem passage ,22, it will be appreciably cooled and pleasant to the smoker.

Likewise, any condensate or foreign matterk in the smoke will deposit inthe bottom of the cap and will not' be conveyed upwardly into the stem passageway.

The pipe can be thoroughly and easily cleaned by merely removing the cap 29 and then removing the sleeve 26 and disassembling the rentime pipe for thorough cleansing. However, the stem passage may be easily cleaned by merely removing the cap and blowing through the stem, which will blow out any foreign matter or con densate downwardly through the annular chamber 2l and forwardly out through the port 28. This is clearly illustrated in Fig. 3 of the drawing in which the pipe is shown with the cap 29 removed for this purpose. Thus, it is seen that even while the bowl is filled with burning tobacco, the smoker may remove the cap andcleanse the passageway 22, the annular `chamber 2l and the port 28 by merely blowing through the stem, which will blow out any matter as previously describedthrough the port 28,. The

smoke and enabling expeditious cleaning of the pipe.

While I have shown the preferred form of my invention, it is to be understood that various changes may be made in its construction by those skilled inthe art without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, what I claim 'and desire to secure by Letters Patent is:

1. A smokers pipe comprising a bowl, a stem having a portion separate from and underlying the bowl, said bowl and stem having registering bores extending through the bottom of the bowl and the underlying portion of the stem, a smoke ktube .projecting downwardly through said bores,

a sleeve arranged over the smoke tube below the stem and connected to the tube for clamping the bowl, stem and tube together, a cap arranged over the lower end of said sleeve and tube, said tube having an open-ended bore formed longitudinally therethrough, said cap, sleeve and tube being provided with passage means` whereby smoke drawn through the lower end of said tube will pass around the sleeve into the bore in said stem around the tube, said steml having apassage communicating with said bore therein.

2. A smokers pipe comprising a bowl, a stem having a portion separate from and underlying the bowl, `said bowl and stem having registering bores of the same diameter extending through the bottom of the bowl and underlying portion of the stem, a sleeve at the underside of the stem aligned with. said bores, an open-ended smoke tube .extending through said bores and connected with the sleeve at the lower end of the latter, the upper end of the smoke tube `abutting the bottom of the bowl interiorly thereof, said stem,

the sleeve andthe pointwhere it engages the l bore-of the stem, said sleeve being lformed with a bore above its connection with the tubeMofv a municating with said chamber, and a cap memsmoker may then replace the cap and continue smoking.

If desired,` theA smoker may'permit a slight amount of atmospheric air in the'annular passageway 32 to commingle with the smoke. Such an air entry may be effected by backing the cap ber tting over the end of lthesleeve and *tube and connected with the sleeve whereby vsmoke drawn from the bowl will travel downwardly ,Y

through the tube aroundy the lower end of the sleeve through said port into said annular cham ber and thence into the passage of the stem.A

3. A smokers pipe comprising a bowl, a stem having a portion separate from and underlying the bowl, said bowl and stem having registering bores extendingthrough the bottom of 4the bowlj and underlying portion of the stem, a sleeve member at the underside of the stem having a bore aligned withv said bores, an open-ended smoke tube extending-through said bores and threadedly engaging the lower lend of the sleeve,

said stem having a smoke passageway formed therethrough communicating therein, said tube engaging the bore of the bowl and the bore of the stem above the smoke passage in the latter, said tube being reduced in external diameter between its connection with thel sleeve and the point where it engages the stem bore to form an annular chamber, said sleeve having a port formed therethrough at a point with said bore` diametrically opposite the point where the passage in the stem communicates with the bore thereof, a cap member tting over the lower end of the sleeve and tube and connected with f the sleeve above the port therein, theinterior dimensions of the cap being so related to the dimensions of the sleeve and tube thata smoke passageway is formedbetween the lower end of the tube and said port around the lower end of the tube and sleeve whereby smoke` from the bowl will pass downwardly through the tube `laterally and upwardly aroundthe lower end of` the tubeand the sleeve and thencelaterally through the portinto the annular chamber` and thence upwardly `through the chambertp the stem passage.
